diatur

Diatur is a passive verb form in Indonesian derived from the root atur, meaning to arrange, set up, or regulate. The prefix di- marks passive voice, so diatur roughly translates as “is arranged” or “is regulated,” depending on context. The construction emphasizes the state or result of being arranged rather than the actor performing the action. The agent responsible for the action can be stated with oleh, or it may be omitted when understood from context.

In everyday and formal language, diatur is used to describe things governed by rules, policies, schedules, or other arrangements. For example: acara ini diatur oleh panitia; harga tiket diatur oleh pemerintah; jadwal pelajaran diatur oleh sekolah. It is common in news reports, official documents, and policy discussions to indicate that certain matters are diatur by law or regulation.

Diatur contrasts with mengatur (to regulate or to arrange actively) and with ditata (arranged in a physical or aesthetic sense). The di- passive construction is a standard feature of Indonesian morphology, enabling statements about governance, order, or setting without naming the agent.
